Paul Tube Fittings, located in Houston, USA, stands out as a leading manufacturer and supplier of Duplex Steel S2205 Tube Fittings, celebrated for their remarkable strength and resistance to corrosion. Crafted from S2205 duplex stainless steel, these fittings merge the best features of austenitic and ferritic stainless steels, offering exceptional protection against stress corrosion cracking, pitting, and crevice corrosion. Paul Tube Fittings provides a diverse selection of tube fitting types, such as elbows, tees, reducers, and unions, all designed for seamless use in chemical processing, marine, and offshore settings. These fittings guarantee high durability and dependable performance in tough, corrosive conditions.
Duplex Steel S2205 Tube Fittings are made up of roughly 22% chromium, 5–6% nickel, 3% molybdenum, and the rest is iron, along with trace amounts of nitrogen and manganese. This well-balanced alloy delivers outstanding mechanical strength, boasting a tensile strength of about 620–880 MPa, along with excellent resistance to chloride-induced stress corrosion cracking. The duplex microstructure ensures high yield strength, toughness, and fatigue resistance. Paul Tube Fittings’ S2205 fittings are precisely machined and feature corrosion-resistant surfaces, making them perfect for high-pressure, high-temperature applications where both strength and corrosion resistance are essential.
